Change USB screen to preserve radio battery

[JimB40]

Existing screen

Proposed

Don't know if OS is working while in USB mode. If so second screen provide possibility to check visually radio battery level
If it's possible to add text with USB mode selected it will provide visual error check (Why there is no disk mounted??? when pressed Joystick by mistake)

@JimB40 the icon is not bad, indeed! Do you have it separately?

[rotorman]

Love the proposed new logo - much more appropriate than the old one in a USB-stick form.
I would add text "USB" to make it clear.

I was going to suggest something similar when 2.4.0 was released, namely that the USB modes be more aligned with what the B&W radios can do... You can see the battery level, time, stick and switch widgets etc.

I.e. in USB Storage mode you could just show an icon like with the joystick mode, and lock touchscreen input and buttons/roller so you can't go into menus.

[raphaelcoeffic]

Oh ok! For my part I thought this would be better for the mass forage mode, as you shouldn't believe you can use the menus or anything else while in that mode. For the 2 others, you can still use the radio normally.

that being said, I’d prefer then proposition 2, but it’s a bit more work. The current one was the most simple to implement ;-)

[pfeerick]

Proposition 2 can be another 'thing' for 2.4.1... just keep the prettier icon for now, and probably dim the screen a bit...

[pfeerick]

@JimB40 Have you still got the icon for this? Rights to use? I'm thinking we could do a black screen, white icon (like first image, but also incorporting USB workding somehow)? Thus the display is mostly blank. Even better if it can be around the dimensions of the original image... https://github.com/EdgeTX/edgetx/blob/main/radio/src/bitmaps/480x272/mask_usb_symbol.png

Then we can try and play with something fancier like the second image in 2.8.

@JimB40 Do you still have the source graphic for this and can it be freely used? Otherwise, this will be moved to 2.11.

[richardclli]

Well, changing the graphics cannot preserve the battery on a LCD display. If you really want to preserve the battery, then you need to lower the brightness instead.

[pfeerick]

Indeed... as it is the backlight brightness that determines the power draw, not the content of the display. I was just focusing on the graphic though for this... if Robert still has it, great as it looks nicer, if not, close and move on.

[richardclli]

But power will be different if OLED display is used instead. However, no color radio is using an OLED display right now.
